Elements Of Remote Sensing According to the Snell's law if an electromagnetic wave is incident in a medium (refractive index n₁) on another medium (refractive index m₂); Both (A) and (B) Neither (A) nor (B) The angle of incidence is equal to the angle of refraction The angle of refraction (θr) is given by sin θ₂ = (n₁/n₂) sin θi Both (A) and (B) Neither (A) nor (B) The angle of incidence is equal to the angle of refraction The angle of refraction (θr) is given by sin θ₂ = (n₁/n₂) sin θi ANSWER DOWNLOAD EXAMIANS APP
Elements Of Remote Sensing "An Electromagnetic wave falls on to a boundary between two losses less homogeneous media with different refractive indices, a part of the wave is reflected back to the incident medium and the rest is transmitted on to the second media". This phenomenon is known as: Fresnel reflection Snell's law Fresnel refraction None of these Fresnel reflection Snell's law Fresnel refraction None of these ANSWER DOWNLOAD EXAMIANS APP
